I had a bad experience jumping with a hoodie, the kind with the joined front pockets. after exiting solo and going on to my back, I noticed something small falling with me in my burble, for a split second I couldn't figure out what it was, it was then that I realized it was the key to my car had fallen out of hoodie pocket. When I instinctivlely reached for it causing me to roll a bit, the wind then hit it and it was gone. I was then educated on the cost of a replacement key for a Honda ($175)
